Publication number: 20230072574Abstract: A buttress is applied to an end effector of a surgical stapler. The buttress is loaded on a platform of a buttress applier cartridge. The end effector is closed upon the platform. An adhesive layer of the buttress secures the buttress to the end effector. The buttress is thus adhered to the end effector when the end effector is opened. The end effector is then actuated on tissue of a patient, thereby stapling the buttress to the tissue.Type: ApplicationFiled: September 22, 2022Publication date: March 9, 2023Inventors: Michael J. Vendely, Trevor J. Barton, Jason L. Harris, Charles J. Scheib, Emily A. Schellin, Prudence A. Vulhop, Steven G. Hall, Victoria Dalessandro, Jackie Donners, Mark D. Timmer, Rao S.

Patent number: 9277919Abstract: A nonwoven compensator for an end effector of a surgical instrument can comprise a plurality of spring fibers dispersed throughout the nonwoven compensator. The nonwoven compensator can be positioned in the end effector such as adjacent to a deck surface of a fastener cartridge that is positioned in the end effector. When a fastener from the fastener cartridge is moved from an initial position to a fired position, the fastener can be configured to engage the nonwoven compensator. The fastener can compress a portion of the nonwoven compensator in a staple entrapment area defined by the fired staple. The spring fibers in the nonwoven compensator can comprise a resilient material and can be deformed when the fastener compresses a portion of the nonwoven compensator. Further, the nonwoven compensator can comprise non-spring fibers, a haemostatic material, and/or a homogenous absorbable polymer matrix.Type: GrantFiled: March 28, 2012Date of Patent: March 8, 2016Assignee: Ethicon Endo-Surgery, LLCInventors: Mark D.
